对原子吸收仪测定金元素稳定性的研究

Study on the stability of determination of gold by atomic absorption spectrometry

先通过标准溶液进行实验样本对象的基础培养,然后,通过更改原子化比值,并计算原子吸收质量系数,来得出实际的测算结果,通过改变相应的硝酸浓度,来观察原子吸收仪测定金元素的相对稳定性。在不同的硝酸浓度下,最终金元素的稳定性并没有发生太大的变化。原子吸收仪在测定金元素稳定性的研究中得出的结果相对较为科学,严谨,具有一定的实际意义。

Firstly,the basic culture of the experimental sample object is carried out through the standard solution,and then the actual calculation results are obtained by changing the atomization ratio and calculating the atomic absorption mass coefficient.By changing the corresponding nitric acid concentration,the relative stability of gold determined by the atomic absorption instrument is observed.At different nitric acid concentrations,the stability of the final gold element did not change much.The results obtained by atomic absorption spectrometry in the determination of the stability of gold are relatively scientific,rigorous and of certain practical significance.
